Thus the play-ofthe balls is limited, and they are kept separated at substantially equalinterva s, so as to afi'ord a firm-support for the type bar all aroundthe bar 3; llgarlic by means of the screw 16 the ball-be "Mg joint maybe made so tight as to prevent either longitudinal or lateral shake ofthe bar ;vvitiioi1t=,p1'eve1it--' ing 'the free swinging mo ementthereof to The type bar is assembled upon the curved supportmgbar 3before the screw 16 is mserted, the hinged eye-segment or flap 13 beingopen so that the maln'eye-se inent 12 may be dropped over the disk 7 .g,he balls having been placed in position, the hinge, p 13 1s closed, andits hasp' 15 is secured to shank B'by screw 16, the latter being ad-'usted until the requisite tightness of the all bearing joint isobtained. j It \iiiil be perceived that type bars may-be made cheaplyand assembled with cascand rapidity; that'the type is accurately guidedto the t pe desired, and readil printingcenter;'that the screws 16 maybe adjusted from time to time to take. up play arisin from wear or,otherwise; that any an may be instantly detached when reassembled,without 'r'eferenceto any ot er type bar; andv that the bar 3' cannotspring durin the printin strokes of the type bars. b g

those in the other set and having a staggeringhor alternate.arrangen'ient with reference thereto; that each type bar hub is composedof separate segmental interior-1y grooved sections, the 'hasp 15 andscrew 16 being provided for-huh ing the sections together;

that the grooves 6 form pivotal" bearings for the type bars, and have acommon 1nternal support consisting of the body of the bar-3; that meansare provided for adjusting the type bar hubs to said grooves or bearins; that in each type bar the segmenta hub sections 12.and 13, takentogether, form an incomplete ring, theserew 16 serving to draw the endsthereof toward which is type bar, forms substantially half of the hub,the section 13 being hingedthereto at a point opposite the junction ofthe hub and shank, the screw '16 serving to bind the 'unthe section 13to the section hinged end of 12; andithat the segmental or segmentshaped.ball bearing groove 23 has abrupt terminations 24 and 25,.which limitthe excursions ofthe ball 28 placed therein.

While I prefer to alternate or stagger. the disks or bearings 7 asshown, still the in vention includes disks, which are offset one fromanother,whethe r or not they have a uniform staggering arrangement andwhile '1 hearings in wish to limit the invention to this particular,direction for the oifsetting in so far as certain features ofmyinvention are-concerned. .It will be seen that the type'barsare-seginentally arranged in two series, the type bars of each serieshaving their pivotal centers situated in a plane that is at an angle toahorizontal plane, or in other words, the

type bar pivot centers of each set are ar ranged in a vertical planeextending transverscly of the machine, that the two planes in which. thepivotal centers of the t pe bars 1 are located are parallel'to each otier, and that the pivotal centers-of the type bars are alternately stagered fore-and aft of the machine. Whi e I prefer to use type bars suchas illustrated, otherkihds ofitypebars may be employed, if desired, inconnection with the novel forins of bearings. 'While sans H i preferhinge of the, segmental I u i 's'pctions to the other, still the hubsections maybe otherwise attached and otherwise formed within the scopeof the inventioin v fl t l1ile I ,prefer to adjust the hubs of the typeb'ars so as to'secure a. close fit of the pelbarjupon' the hanger, otherprovision or adjnstment ma ,be made, orif desired, ,Qthere maybe no ajustment. ",While I prefer to. insert anti-friction balls between thehired bearings and the type bar hubs, still, soifajr as certain novelfeatures of the iiwen:

:3 a9, 7 Although I show the'type bars hung upon a setof hangers formedintegral upon 'a sin-,

I blievefmyself tobe-thefirst to place a pluralityof offset converging bearings side yside and eneircle them by type barhubs,

with or without hearing balls.

I prefer to form the, offset or stagger by the, type barhubs. WhiIe YIillustrate a the 'radius may vary as desired. The

series of exterior annular converging stag-J g slightly, producing atensiion" o f 'the hinged section toward the axis of the type bar, so asto take up automatically any wear that may occur in the bearing orin'theballs, and also to compensate for any'imperfecti'ou- 70 of theballs. ,The parts maybe'so formed that when the hasp 15'is put under alight tension bythescrew 16, a 'pe'rfect'fit of' the balls in thebearing is secured and this fit isconstantly maintained bythe capabilityof the parts to adjust themselves automatically as wear occurs. Manyother changes in "details of construction and arrangement may beresorted" to within the"scope"'of the invention, and'parts of-myimprovements may be 'used without'othe'rs.
